CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 597,57 5, dated January18, 1898.-

Application filed May 12, 1897.

To ctZZ whom, it may concern:

Be it known that I, CHRISTOPHER DUTCH- BURN, of I-Iighfield, in theProvince of Ontario and Dominion of Canada, have. invented a new andImproved Car-Coupler, of which the following is a full,clear,and exactdescription.

This invention is a car-coupler of that class in which pins and linksare used and in which the pins and links are operated through the mediumof' rock-shafts mounted at the ends of the cars and extending to thesides thereof to avoid the necessity of trainmen passing betweenthecars.

This specification is the disclosure of one form of my invention, whilethe claims define the actual scope of the conception.

Reference is to be had to the accompanying drawings, formin g a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side elevation of the inven- Fig. 2 is a sectional view onthe line 2 2 of Fig. 3. Fig. 3 is a sectional view on the line 3 3 ofFig. 2, and Fig. 4 is an end elevation of the invention.

The draw-bars 5 carry the coupling-heads 6, which have throats 7 andcavities 8, subjacent to the throats, the cavities 8 being divided by avertical partition 9. Extending transversely through each coupling-headis a shaft 10, each shaft carrying two liftingecams 11, fixed on theshafts and respectively located within the cavities 8 The earns 11 serveto lift the links, as indicated in Fig. 2, which lifting of the links isnecessary to the coupling operation.

Pins 12 slide vertically through passages 13, respectively, formed inthe rear of the coupling-heads. Each coupling-head has ahorizontally-sliding plate 14, crossing the passages 13 of thecoupling-head and serving to support the pins 12, as shown in Fig. 3.The plate 14 of each coupling-head is pivoted to a wing 15, hinged toone side of the couplinghead 6 and pressed against the coupling-head bya leaf-spring 16. Each coupling-head has a ledge 17 overhanging the wingand spring 16, whereby to protect the same. Each wing Serial No.686,194. (No model.)

operation the pins 12 are supported out of the throats 7 by the plates14:. The link 9, when projected into one of thethroats, engages the lug18 thereof and pushes outward the wing 15, which in turn withdraws thecorresponding plate 14 and allows the pin 12 to drop into engagementwith the link 9.

Mounted at each end of the car are two rock-shafts 20 and 21, having attheir ends crank-arms 22 and 23. An intermediate por tion of eachcrank-shaft also has a crank-arm 24 and 25. The crank-arm 25 is pivotedto a link 26, in turn connected to the pin 12 of the adjacent coupling.The crank-arm 24 is pivoted to a link 27, which is pivoted in turn to acrank 28, fixed on the shaft 10 of the 'adjacent coupling. By thesemeans the cams l1 and the pins 12 may be manipulated readily withoutrequiring the trainmen to pass between the cars. flange 11 at its outerupper corner. Between these ribs in each pair of cams the links 9 lie.

Having thus described my invention, I claim as new and desire to secureby Letters Patent-- 1. The combination with a coupling-head having athroat and a ledge extending out from one side of the throat, of a platesliding horizontally through the coupling-head and serving to support apin out of the throat, a wing attached to the plate and having a lugprojecting into the throat the wing being located beneath the ledge ofthe coupling-head, and a spring pressing the wing inward and alsolocated beneath the ledge.

2.. In a car-coupling, the combination of a coupling-head having avertical passage run therethrough to receive the pin, and having ahorizontal passage intersecting in the vertical passage, a plate slidingthrough the horizontal passage and capable of supporting a pin in thevertical passage, a wing pivoted to the outer side of the coupling-headand attached to the plate, and a spring pressing the wing to hold theplate inward, the coupling-head having a ledge overhanging the wing toprotect the same.
